  Log:
  SVN rev 197062 on 2009-09-10 12:58:37Z by jhb
  
  Don't malloc a buffer while holding the prison0 mutex.  Instead, use a loop
  where we figure out the hostname length under the lock, malloc the buffer
  with the lock dropped, then recheck the length under the lock and loop again
  if the buffer is now too small.
